Проведен анализ методики определения значений расчетных параметров, применяемых при моделировании пожаров в программном комплексе FDS для расчета динамики задымления в помещении. Показано, что существующие подходы к определению значений расчетных параметров дымообразования справедливы только при полном сгорании материалов в условиях стандартных испытаний на дымообразующую способность. Для учета неполноты сгорания материалов проведен анализ экспериментальных данных по остатку массы материалов, для которых определен коэффициент дымообразования. В результате в расчетные формулы введены соответствующие коэффициенты, значительно повышающие точность проводимых расчетов динамики задымления в помещении.
